As it stands, Google Play and Apple’s App Store have around 700,000 live apps each, followed by Windows with 126,530 and Amazon with just over 50,000 apps. As app numbers continue to increase, so is the competition for search-friendly and visible apps.

A number of people are starting to talk about app store SEO as developers and marketers look for ways to ensure their apps can be found across the app stores.

We’ll be focusing on both the App Store and Google Play for this post, solely because there currently isn’t enough research on SEO for Windows Marketplace or Amazon's Appstore.
